The wheel rim 2 is a cylinder of suitable with spokes 3 arranged in any having inwardly proial flanges 4 at its edges.

What I claim is:

1. In a traction wh sockets formed by the gui spring chambers are formed integral with each other and with the tire projections 8 on the guide blocks are arranged in the spaces between the spring The ends of each tire section have plates 20 which overlap the edges of the rim and which are provide guide-slots 21. Bolts 22 pass through holes he slots 21 are and limit the and in the rim flanges 4:, and t slidable over the bolts 22 radial movements of the tire sections guide them so that they slide freely. Helical springs 24L- are arranged in the spring chambers between the wheel rim, and disks 25 wheel rim on the axes of to hold their inner end coils in The spring chambers have jecting lips 26 at their botto springs so that the stops 26 and 1 contact. As the wheel runs on the road the tire sections are presse the pressure of the helical springs,

to roughness of road are in a great measure counteracted. Portions of the projections 1a on the tire sections maybe arranged to form guard fingers 30 which project from oneip over the spaces between theplates and for a short distance over the adjacent plates, to prevent stones from becoming wedge tween the edges of the plates. These fingers constrain the adjacent plate gether when they overlap them, may be dispensed with if desired, or may me made to overlap the spaces only.

The tire sections have notches or slots 15 in their edges to give access to the fastening screws 6, and the hape and are arranged so that the projections on the edges of each plate fit v recesses of the adjacent plates.

2. In a traction wheel, the combination, with a wheel rim, of guide blocks secured around the wheel rim and provided with socket sections and projections arranged alternately upon their side edges and in and forming guides, tire sections provided chambers which are slidable radially in the rim and forming staggered and stop devices which i l l l with staggered spring;

3. In a traction wheel, the combination,

4.
